stationary, the. burnisher being shown as mountedon a flexible shaftconnected to an Be it known that l, Gnonon owns, a subject of the Kingof Great Britain and lreland, residing at 100 Evering road, Stokellewington, in the county o't London, England, have invented certain newand use ullrnprovements in Burnishing anc Scaritying Devices, and Idohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to makeand use the, same,reierence being had to theaccompanying draw'n'gs, and to letters or figures of reference markedthereon, which form a part of this specification.

This invention relates to burnishing and scarifying apparatus, theobject of the inburnisher in the distended condition as-.

the combustion chamber of an internal coinnisliedpor scarilied by aburnisher of the form shown in Figs. 1 and 2. Figs. 4: and 5 arerespectively, a front elevation and a side sectional elevation of asecond form of barnisher in th'e distended condition.

In carrying out the invention according to one form the burnisher a,Fig. 1, comprises a plurality of steel links or chain mail so as to forma circular disk, when rotated, as indicated in Fig. 2. The diskis'niounted at or near its geometrical center on a socket I), screwed orotherwise secured to :the end of a flexible shaft 0, which may beincased as scaritier which can be readily passed through comparativelysmall and awkwardly shaped apertures or passages into interiors ofvarious shapes and dimensions, and then expanded and rotated within saidinteriors so as to burnish or scaiity the Walls oi said interiors orother parts therein, theburnisher or scariiier automatically adaptingitself to irregularities or variations in the shape tor f. q

So long as the shaft 0, is still or only slowly rotating, the bnrnisheror scarifier a, remains in a collapsed and compact form as the operator.

The invention is particularly applicable to the buruishing or scarityingot' the comhustiou chambers, piston-heads and jj like parts oi? internalcombustion engin to remove carbon and other depos' y from without thenecessity for ,(lismoiinting the cylinders. y i Q The apparatus,according to the inven* tion, comprises a burnisher or'scai'iiier, consisting ot a plurality of steel or like elements loosely linked togetherand mounte on the end of a flexible shaft or extension thereof, whichmay be rotated at a suitable speed by any suitable means, such as anelectric or other motor. i The elements are preferably in the formot'stcel links, wires or chain mail and are also preferably intermesh'edand symmetrically arranged in the term of a flexible disk of circular,square or other outline mounted at or near its geometrical center onthe. shaft. Some of the elements, for instance,- on the outer edge ofthe disk, may. be provided with serrations or cutting teeth.

The accompanying drawings illustrate easily inserted through anyconvenient orilice, such as a valve port 7, Fig. 3, or spark plug hole,into the combustion chamber lb, of the cylinder 1', which is to beoperated upon, the piston In, of such cylinder being brought into itsinnermost position as indicatedin tions of the cylinder being exposed tothe action of the burnisher or scarifier. When the burnisher orscaritier a, is rotated it expands, under centrifugal force, and adaptsitself to the irregular shape of the interior surfaces to; which it isapplied, and while rotating it may be moved in any require direction bythe operator, by means 0 th flexible shaft 0, or casing d, thereof, thusscaritying and loosening the deposits wit which the burnisher orscarifier a, is brought into contact.

cated in Figs. 4 and .5, some of the elements of the burnisher orscarifier may comprise links a, as inthe form previously described,

but others, r'or instance. at the outer edges of the disk, may be in theform of plates Z, having serrations or cutting teeth at.
